IMPROVEMENT IN KILNS FOR DRVING The Schedule referred to in these Letters Patent and part of the name.

To all whom it muy concern Be it known that I, JOHN A. KEMER, of the city,

county, and State of New York, have invented a new and useful Improvement in Kilns for Drying Malt and other substances, of which vthe following isa full, clear, and exact description, reference lbeing hadto the accompanying drawing forming part of this speci-v fication, and in which- I Figurel represents a sectional plan of a malt-kiln constructed in accordance with my improvement, and Figure 2, a vertical section of the same, taken transversely through the axis of the drying device. Similar letters of 4reference indicate corresponding parts.

My invention consists in a rotary drier of annular form, and in which the one or both of the peripheries 'are mainly of a perforated or screen-like construction,

as may also be its sides, said cylinder revolving in a heated chamber, and serving by its annular construction to vmore thoroughly agitate and expose the substance to be dried than an entire cylinder is capable of doing.

The invention also includes a combination of inner and outer buckets within an annular revolving drier,

-whereby the malt or substance being dried is not only eectually agitated, but kept separated, as regards bulk, and tossed to and fro between the buckets during their rotation in common.

The invention likewise consists in a combination of opening-and-closing mechanism with a system or se- 1 ries of valves arranged on the outer periphery of the revolving drier, for automatically opening and closing inlets and outlets, with which the drier is provided, to effect the admission to and discharge therefrom of the malt or snbstanee'under treatment.

In the accompanying drawing- A represents a room or chamber designed to be heated inany suitable manner, and lprovided with a door, a. c

B is.the`revolving drier secured to a horizontal shaft, b, which may be driven by gearing from a primary shaft. `This vdrier is of annular'gform with its vouter -periphery or outer and inner peripheries, as also, if desired, .its sides perforated or -of lscreen-like construction.

Said 'perforated annular dri'er it is furthermore prelferred to construct with inner and outer buckets c and d, arranged in alternate relation around the two peripheries on the inside of the drier, and preferably of reverse curvilinear form at their ends, and with leaves or projections c. on the exterior of the advance en ds of the inner buckets, all as clearly representedin tig. 2. A

The outerperiphery of the drier is provided with inlets and outlets, controlled by gates or valves corresponding in number and arrangement to the outer row of buckets, for the purpose of charging each cmbined setof inner and outer buckets with the malt to be dried, and of discharging the same therefrom when required. These valves may bevariously constructed,

but they are here shown as double vibrating valves,f, -swinging on centers, as at g, and controlling openings h in the drier,

O is a hopper for .supplying the drier with malt by opening any or each of the valves f, as, in the rota-f `struction, which not onlygives au extended surface exposure, but does' away with` any accumulation of v the malt atthe center of the drier,` and secures a more perfect agitation of it accordingly. d

Another peculiarty is" itsarrangement of inside-v and-outside buckets, which, as the drier. is rotated,

serve to toss the malt from the inner tothe outer buckets and `lack again, and to more perfectly distribute and agitate it. Malt may, by this rotary drier, be dried much more uniformly, apidly, and with inlinitely lesslabor than ina malt-house as1 heretofore done.

Combined with the gates orvalves f is shown mech anism. for automatically opening and closing them, or of keeping them opened o'r closed, as required. Thus, D is a vrock-shaft operated by a handle, i. This rockshaft, by means of a rod, K and suitable connections, serves to rock two counter-shafts, l l, arranged on op'- posite sides ofthe hopper, and accordingly as the handle t is thrownv to the position represented for it by full and dotted lines, sets or adjusts toes m m on the rock-shaftsl l, so that they are either made to come in contact with 'or clear projections 4n n' on the valves j', as the drier B is rotated inthe direction indicated by the arrow a'. When the lever or handle i is moved to its position, shown in full lines, the toe m serves, as the projections n strike it, to -open the valves to admit malt from the hopper as the openings h pass under the latter, aud the toes m afterward operate ou the projections n to close'the valves. The revolving drier being thus charged with a certain quantity of malt in each set of buckets the lever i-is shifted to the position shownl by dotted lines, which puts the toes an m out of contact with theprojections .n n', thus causing the drier to rotate with its valves.

shaftD, 'serves to throw and hold said mechanism in its opening-and-closing position on the valves, and a spring, 1), catching'or bearing on the lever fi, operates to hold said mechanism free of any action on' the valves.

lA somewhat similar mechanism may be used to open the valves when it is required to effect discharge l.' A revolving and perforated annular drier, -substantia'lly as speciied.

2. The combination of inner and outer buckets'c and d with a revolving and perforated annular drier, essentially as described. v

3. The combination,witl1 the gates or valves arranged around the outer peripher :of the revolving drier and with the buckets which said valves control,

when required, the valves as they pass under the hopper that supplies thedrier, substantially as specified.

ing device or toe q andmechanism for controlling the same with the revolving drier B and its valves and buckets, essentially as and for the purpose' herein set forth.
